F-Series: F131

Field mount - Batch controller

with two-stage control, pulse output and analog output in relation to the flow rate

The F131 offers, in addition to the standard batch control functions, an analog output signal in relation to the displayed flow rate. The operator can enter a batch quantity easily or execute repeating batches.
During the batch, the preset value and flow rate are displayed simultaneously with the batched or remaining quantity. The automatic self-learning overrun correction will ensure an accurate batch every time. On-screen engineering units are easily configured from a comprehensive selection.

Advantages
  • Robust IP66, IP67 (NEMA Type4X) field enclosure. It is so rugged, you can even stand on it!
  • Intrinsically Safe available - ATEX and IECEx approval for gas and dust applications.
  • Programming can be done by your own crew, with the sensible menu-driven structure, saving cost and irritation. Know one, know them all!
  • Very diverse mounting possibilities: walls, pipes, panels or directly onto outdoor sensors.
Application overview F131

Features

  • Large display shows running batch value together with preset value or flow rate.
  • Analog output reflecting the actual flow rate.
  • Flow rate: seven 8mm (0.31") digits.
  • Two-stage control for batching larger quantities.
  • Self-learning overrun correction.
  • Easy operation to enter a batch value and to control the process.
  • Count-up and count-down function available.
  • Scaled pulse output reflecting accumulated or batched total.
  • Actual batched quantity: seven 17mm (0.67") digits.
  • Preset value: seven 17mm (0.67") digits during programming and 8mm (0.31") digits during batchprocess.
  • Total - resettable: seven 17mm (0.67") digits.
  • Accumulated total - not resettable: eleven 8mm (0.31") digits.
  • LED backlight.
  • Auto backup of settings and running totals in EEPROM memory.
  • Ambient temperature: -40°C to +80°C (-40°F to 176°F).
  • Various accessories are available for this product.
  • The F-Series is so rugged, even a truck can stand on it!

Flowmeter Inputs

  • Pulse type inputs:
    Reed-switch, open collector, NAMUR, NPN/PNP pulse, Sine wave (coil), active pulse signal.
  • (0)4 – 20mA.

Status Inputs

  • Remote control: start.
  • Remote control: pause / stop.

Pulse Outputs

  • Function: Scaled pulse output according to accumulated or batched total (e.g. a pulse every 3.25 gallons).
    Max. frequency: 500Hz.
    Adjustable pulse length from 0.001 sec. to 9.999 seconds.
  • Type: One passive NPN transistor, active PNP transistor or isolated electro-mechanical relay.
  • Remark: With pulse output one-stage control only and no communication available.

Alarm Outputs

  • None.

Analog Outputs

  • Function: Re-transmitting the flow rate - the output can be scaled to any range (e.g. 200 L/min to 1200 L/min).
  • Type: One passive isolated, floating or loop powered 4 – 20mA output or one active (0)4 – 20mA or 0 – 10V DC output.

Control Outputs

  • Function: Control outputs for one- or two-stage batching with active overrun correction.
  • Type: Two passive NPN transistors, active PNP transistors or isolated electro-mechanical relays.
  • Remark: With two-stage control no pulse output available.

Applications

  • The F-Series is your first and best choice for field mount indicators in safe and hazardous area applications. Especially in harsh weather conditions like rain, snow, salty atmospheres and temperatures between -40°C up to +80°C (-40°F up to 176°F).
  • For batching small up to very large quantities including flow rate indication and signal re-transmission.
    Alternative basic model: F030, F130. Alternative advanced model: F136 or even more advanced N-Series.
    Basic DIN panel mount batch controller: D030.
